Unrepaired Congenital Heart Disease in Childhood: A Case of Ventricular Septal Defect and Double-Chambered Right Ventricle.

Congenital heart diseases are structural abnormalities of the heart with functional repercussions on the patient's hemodynamics. At the time of diagnosis, most patients are in childhood, and the clinical course exhibits a wide spectrum of severity, ranging from mild conditions that do not affect the quality of life to severe presentations that may lead to death. Under this concept, we present the case of a 45-year-old patient who was diagnosed in childhood with a ventricular septal defect for which he did not receive any treatment or intervention.
